Light-guiding modules and LED lamp using the same

Abstract

An LED lamp includes a base, an LED module having a plurality of LEDs mounted on a top of the base, and a light-guiding module fixed on the LED module. The light-guiding module includes a plurality of mounted plates and a plurality of inserted plates intersecting and engaging the mounted plates. The mounted plates and the inserted plates cooperatively define a plurality of cavities to receive corresponding LEDs therein for guiding and reflecting light generated by the corresponding LED in a predetermined manner.

       2. The LED lamp as claimed in  claim 1 , wherein each cavity comprises an upper opening and a lower opening in communication with the upper opening, each lower opening aligning with and directly facing the corresponding LED of the LED module. 
     
     
       3. The LED lamp as claimed in  claim 2 , wherein the lower opening is smaller than the upper opening. 
     
     
       4. The LED lamp as claimed in  claim 1 , wherein each of the mounted plates defines a plurality of slit sets receiving the inserted plates therein. 
     
     
       5. The LED lamp as claimed in  claim 4 , wherein each of the slit sets comprises a first slit and a second slit, the first and second slits extending downwardly towards the LEDs from a top edge of each mounted plate toward each other. 
     
     
       6. The LED lamp as claimed in  claim 5 , wherein the first slit of each slit set angles at an acute angle downwardly and rightward from the top edge. 
     
     
       7. The LED lamp as claimed in  claim 5 , wherein the second slit of each slit forms angle larger than that of the first slit downwardly and leftward from the top edge. 
     
     
       8. The LED lamp as claimed in  claim 5 , wherein bottom ends of the first and second slits are defined at a distance from a bottom edge of each mounted plate. 
     
     
       9. The light-guiding module as claimed in  claim 1 , wherein each of the mounted plates and the inserted plates is a single flat plate. 
     
     
       10. The light-guiding module as claimed in  claim 9 , wherein each of the inserted plates crosses each of the mounted plates. 
     
     
       11. A light-guiding module fixed on an LED module to guide and reflect light emitted by a plurality of LEDs of the LED module, comprising:
 a plurality of mounted plates; and 
 a plurality of inserted plates intersecting and engaging with the mounted plates, the mounted plates and the inserted plates cooperatively defining a plurality of cavities each receiving a corresponding LED therein, each of the cavities being encircled by two neighboring mounted plates and two neighboring inserted plates, the mounted plates and the inserted plates cooperatively guiding and reflecting light generated by the corresponding LED in a predetermined manner, each of the cavities comprising an upper opening and a lower opening in communication with the upper opening. 
 
     
     
       12. The light-guiding module as claimed in  claim 11 , wherein the amount of cavities varies with the amount of mounted plates and inserted plates. 
     
     
       13. The light-guiding module as claimed in  claim 11 , wherein the lower opening is smaller than the upper opening. 
     
     
       14. The light-guiding module as claimed in  claim 11 , wherein each of the mounted plates defines a plurality of slit sets receiving the inserted plates therein. 
     
     
       15. The light-guiding module as claimed in  claim 14 , wherein the second slit of each slit set angles about 87° downwardly and leftward from the top edge. 
     
     
       16. The light-guiding module as claimed in  claim 14 , wherein each of the slit sets comprises a first slit and a second slit, the first and second slits extending downwardly from a top edge of each mounted plate toward each other. 
     
     
       17. The light-guiding module as claimed in  claim 14 , wherein the first slit of each slit set angles about 50° downwardly and rightward from the top edge. 
     
     
       18. The light-guiding module as claimed in  claim 11 , wherein each of the inserted plates crosses each of the mounted plates. 
     
     
       19. The light-guiding module as claimed in  claim 18 , wherein each of the mounted plates and the inserted plates is a single flat plate.
